Donghui Jeong studies the origin and evolution of the Universe from astrophysical observations, including the temperature anisotropies and polarization of the cosmic microwave background, the large-scale distribution of matter and galaxies, and the distribution and spectrum of gravitational-wave sources. His current research focuses on unveiling the building blocks of the concordance Lambda-CDM cosmology model such as cosmic inflation, dark energy, and dark matter. At the moment, he is analyzing the HETDEX galaxy survey data to measure the dark-energy properties at an early time, and preparing for the A-SPEC galaxy survey that will map out the local dark-matter distribution from the observed peculiar velocity field.
